FIELD OF THE DISCLOSURE

The instant disclosure relates to hair treatment compositions that areparticularly useful for improving the quality of hair. Also disclosedare kits that include the hair treatment compositions and methods forusing the hair treatment compositions.

BACKGROUND

Many consumers desire to use cosmetic and care compositions that enhancethe appearance of keratinous substrates such as hair, e.g., by changingthe color, style, and/or shape of the hair, and/or by imparting variouscosmetic properties to hair, such as shine and conditioning. Many of theknown compositions and processes for enhancing the appearance of hairinvolve chemical treatments to the hair.

The process of changing the color of hair, for example, can involvedepositing an artificial color onto the hair which provides a differentshade or color to the hair, and/or lifting the color of the hair, suchas lightening the color of dark hair to lighter shades. The process oflifting the color of hair, also known as lightening (or bleaching),generally requires the use of oxidizing agents. Lightening of hair istypically evaluated by the variation in tone height before and after theapplication of a hair color-altering composition onto hair. Thisvariation corresponds to the degree or level of lightening or lift. Thenotion of “tone” is based on the classification of the natural shades,one tone separating each shade from the shade immediately following orpreceding it, which is well known to hairstyling professionals. The toneheights or levels can range from 1 (black) to 10 (light blond), one unitcorresponding to one tone; thus, the higher the number, the lighter theshade or the greater the degree of lift.

Additionally, there are many techniques and compositions for styling oraltering the shape of hair. For example, hair care products referred toas “hair relaxers” or “hair straighteners” can relax or straighten curlyor kinky hair, including wavy hair. Straightening or relaxing the curlsof very curly hair may increase the manageability and ease of styling ofsuch hair. Compositions for permanent waving the hair will impart a curlor a wave to otherwise straight hair. Different types of compositionscan be applied onto hair in order to change its shape and make it moremanageable, such as alkaline and acidic compositions. Hair relaxers,straighteners, perms, and/or waves may either be applied in a hair salonby a professional or in the home by the individual consumer.

While dyeing or color lifting compositions can effectively alter thecolor of hair, and relaxing, straightening, perming, and wavingcompositions can effectively alter the shape of the hair, these chemicaltreatments can damage the hair fibers and/or irritate the scalp. Thus,in order to reduce or avoid damage to hair, as well as to improve thecosmetic performance of the compositions, the use of new and additionalcomponents and novel combinations of ingredients are continuouslysought.

However, the choice of components or combinations of ingredients couldpose difficulties insofar as they cannot be detrimental to othercosmetic attributes such as ease and uniformity of application, rheologyor viscosity properties and stability of the compositions, color depositand target shade formation, and/or result into more disadvantages suchas increased damage or a less healthy look to the hair. It wouldtherefore be desirable to provide the consumer with compositions andmethods that can chemically treat the hair while providing othercosmetic advantages such as shine, conditioning, fiber strength, and/ora healthy appearance to the hair, but avoiding or minimizing damage tothe hair.

Further, both natural and sensitized or chemically treated hair cancontain several kinds of negatively charged moieties, for example,carboxylates (resulting from the hydrolysis of amino acids and thioesterbonds) and/or sulfonates (resulting from the oxidation of disulfidebonds). These negatively charged moieties can degrade the cosmeticproperties of the hair. Moreover, when hair is chemically treated ordamaged, the disulfide bonds in hair (disulfide linkages between twocysteine units) can be reduced or broken, resulting in the formation ofthiol groups and/or cysteic acid. There is therefore an ongoing need forhair treatment compositions which help to improve the properties ofhair.

In further embodiments, the inulin is presentin an amount of from about 0.1 to about 10 wt. %, or about 0.5 to about2.5 wt. %.

Prosolvent

As used herein “prosolvent” refers to a solvent system which enhancesthe performance of the composition by enhancing penetration of theactive ingredients into the hair. In one or more embodiments, theprosolvent comprises one or more glycol compounds. In furtherembodiments, the glycol compounds are selected from the group consistingof hexylene glycol, butylene glycol, propylene glycol, and combinationsthereof.

In one or more embodiments, the prosolvent comprises a mixture of twoingredients in a ratio ranging from about 1:2 to about 2:1, or morespecifically 1:1. In some embodiments, the prosolvent comprises hexyleneglycol and butylene glycol. In one or more embodiments, the prosolventcomprises propylene glycol in addition to hexylene glycol and butyleneglycol.

While not wishing to be bound to any particular theory, it is thoughtthat the presence of the prosolvent increases the efficacy ofpenetrating actives such as maleic acid. The prosolvent may also act asa surfactant and assists in stabilizing the emulsion. Emulsion stabilityis a particularly important effect when low pH ingredients are present(e.g., maleic acid) because such low pH ingredients can have a negativeeffect on emulsion stability. Thus, it is thought that the prosolventworks to counteract the negative effect of low pH ingredients onemulsion stability as well as assisting active penetration to thecortex.

Preservatives

One or more preservatives may be included in the compositions describedherein for treating hair. Suitable preservatives include, but are notlimited to, glycerin containing compounds (e.g., glycerin orethylhexylglycerin or phenoxyethanol), benzyl alcohol, parabens(methylparaben, ethylparaben, propylparaben, butylparaben,isobutylparaben, etc.), sodium benzoate, ethylenediamine-tetraaceticacid (EDTA), potassium sorbate, and/or grapefruit seed extract, orcombinations thereof. More than one preservative may be included in thecomposition. Other preservatives are known in the cosmetics industriesand include salicylic acid, DMDM Hydantoin, Formaldahyde, Chlorphenism,Triclosan, Imidazolidinyl Urea, Diazolidinyl Urea, Sorbic Acid,Methylisothiazolinone, Sodium Dehydroacetate, Dehydroacetic Acid,Quaternium-15, Stearalkonium Chloride, Zinc Pyrithione, SodiumMetabisulfite, 2-Bromo-2-Nitropropane, Chlorhexidine Digluconate,Polyaminopropyl biguanide, Benzalkonium Chloride, Sodium Sulfite, SodiumSalicylate, Citric Acid, Neem Oil, Essential Oils (various), LacticAcid, and Vitamin E (tocopherol).

The total amount of the one or more preservatives, when present, mayvary. In some cases, the total amount of the one or more preservativesis about 0.01 to about 5 wt. %, about 0.01 to about 4 wt. %, about 0.15to about 1 wt. %, or about 1 to about 3 wt. %, based on the total weightof the composition.

Suitable components, such as those listed in the instant disclosure(including those listed above), may be included or excluded from thehair styling compositions depending on the specific combination of othercomponents, the form of the compositions, and/or the use of theformulation (e.g., hair spray, cream, paste, conditioner, etc.).

Methods

Another aspect of the invention pertains to methods of using the hairtreatment compositions described herein. The methods generally compriseapplying any of the hair treatment compositions described to hair. Thehair treatment compositions may be useful in a variety of settings, andeither for treated or untreated hair. Use on treated hair can includechemically relaxed hair. The hair treatment composition may be appliedpost relaxer but before neutralizing shampoo, after neutralizingshampoo, in or as a conditioner, or as a leave in treatment after therelaxation process. Use on untreated hair may include as part of ashampoo, part of a conditioner, as a pre-treatment, or after washing thehair as a leave-in treatment.

Methods of treating hair according to the disclosure may includeapplying a hair treatment composition of the instant disclosure to thehair (wet, damp, or dry hair), allowing the hair treatment to remain onthe hair for a sufficient amount of time, and rinsing the hair treatmentcomposition from the hair. The hair treatment composition may be appliedto the hair before, during, or after other hair treatment compositions(e.g., a chemical relaxer composition, a shampoo, a conditioner, alotion, a gel, etc.).

As mentioned previously, the hair treatment compositions areparticularly useful for treating chemically treated hair. In some cases,a hair treatment composition is applied to the hair shortly after achemical treatment composition is rinsed from the hair (e.g., withinabout 5, 10, 15, 20, or 30 minutes from when the chemical treatmentcomposition is rinsed from the hair), while the hair is still wet ordamp. The hair treatment composition may be allowed to remain on thehair for a period of time, for example from about a few seconds (1, 3,5, or 10 seconds) to about 10, 20, or 30 minutes, or longer. In somecases, the hair treatment composition is applied to the chemicallytreated hair shortly after a chemical treatment composition is rinsedfrom the hair; and after applying the hair treatment composition, thehair is subsequently treated with a shampoo and/or a conditioner, or aconditioning shampoo (all-in-one shampoo/conditioner). The hairtreatment composition may be rinsed from the hair prior to applicationof a shampoo and/or a conditioner, or a conditioning shampoo, or it maybe allowed to remain on the hair during shampooing and/or conditioningand rinsed from the hair with the shampoo or the conditioner, or withthe conditioning shampoo. For example, the hair treatment compositionmay be applied to the hair and without rinsing the hair treatment fromthe hair, a shampoo (or conditioner or conditioning shampoo) issubsequently applied to the hair (layered onto the hair treatmentcomposition already applied to the hair). Both compositions (the hairtreatment composition and the shampoo, conditioner, or conditioningshampoo) are rinsed from the hair together.

Moreover, the hair treatment composition may be combined with a shampooand/or a conditioner, or with a conditioning shampoo, prior toapplication to the hair. Combining the hair treatment compositions withone or more additional hair treatment compositions (e.g., a shampoo, aconditioner, a conditioning shampoo, a rinse, etc.). For instance, thehair treatment composition may be mixed with a shampoo (or conditioneror conditioning shampoo) prior to application to the hair. In this case,the mixture of the shampoo (or conditioner or conditioning shampoo) andthe hair treatment composition are simultaneously applied to the hairduring the cleansing and/or conditioning process and simultaneouslyrinsed from the hair. Alternatively, the hair treatment composition maybe layered on top of (or lathered into) hair to which a shampoo (orconditioner or conditioning shampoo) has already been applied or viceversa. In this case, the hair treatment composition may be applied tothe hair first and without rinsing it from the hair, a shampoo (orconditioner or conditioning shampoo) is then subsequently applied to thehair. Alternatively, the shampoo (or conditioner or conditioningshampoo) may be first applied to the hair and without rinsing theshampoo (or conditioner or conditioning shampoo) from the hair, the hairtreatment composition is also applied to the hair. Then, thecompositions are simultaneously rinsed from the hair.

Described above is the individual application of a hair treatmentcomposition or the combined or layered application of a hair treatmentcomposition with another composition (e.g., a shampoo, conditioner,conditioning shampoo, etc.). In some cases, a hair treatment compositionis individually applied to the hair and also combined or layered withanother composition (e.g., a shampoo, conditioner, conditioning shampoo,etc.) that is also applied to the hair. For example, a hair treatmentcomposition may be applied to the hair. Subsequently, with or withoutrinsing the hair treatment composition from the hair, anothercomposition (e.g., a shampoo, conditioner, conditioning shampoo, etc.)in which the hair treatment composition has been mixed may be applied tothe hair.

When combined with another composition (e.g., a shampoo, conditioner,conditioning shampoo, etc.), the hair treatment composition may be mixedwith or used with in a ratio of about 1:10 to about 10:1, about 1:5 toabout 5:1, about 1:3 to about 3:1, about 1:2 to about 2:1, about 1:1 toabout 4:1, about 1:1 to about 3:1, or about 1:1 to about 2:1 (hairtreatment composition of the instant disclosure:another composition).

The hair treatment compositions may be allowed to remain on the hair fora minimum amount of time before being rinsed from the hair, but allowingthe hair treatment composition to remain on the hair for an extendedperiod of time is not needed. Conveniently, the hair treatmentcompositions can be applied and allowed to remain on the hair for aperiod of time that is typical for regular shampooing and/orconditioning. For example, the hair treatment composition (whethercombined with another hair treatment composition such as a shampoo orconditioner) may be applied to the hair and allowed to remain on thehair for a few seconds (1, 2, 3, 5, or 10 seconds) up to about 1, 2, 5,10, 20, or 30 minutes, or longer.

When the hair treatment composition is not applied to the hair,simultaneously with another composition (e.g., a shampoo, conditioner,conditioning shampoo, etc.), the hair treatment composition may beapplied to the hair immediately after or before the hair is treated withanother composition (e.g., a shampoo, conditioner, conditioning shampoo,etc.). For example, the hair treatment compositions may be applied tothe hair within about 1, 2, 5, 10, or 20 minutes before or after anothercomposition is applied to the hair.

Kits

The hair treatment compositions of the instant disclosure may beincorporated into a kit. For example, the kits may include at least onehair treatment composition according to the instant disclosure and oneor more additional hair treatment compositions, for example, a hairrelaxer composition, a shampoo, a conditioner, etc. The various hairtreatment compositions are separately contained in the kits. In someinstances, the kits include one or more hair treatment compositions(according the instant disclosure), a shampoo, and/or a conditioner, allof which are separately contained. The kits may also include one or morehair treatment compositions (according the instant disclosure), achemical relaxer composition, and optionally a shampoo and/or aconditioner. Instructions, mixing components, brushes, gloves, measuringtools, etc., may also be included in the kits.

The results show a synergistic effect when all three of inulin, maleicacid and prosolvent are present in all of the hair attributes.

The foregoing description illustrates and describes the disclosure.Additionally, the disclosure shows and describes only the preferredembodiments but, as mentioned above, it is to be understood that it iscapable to use in various other combinations, modifications, andenvironments and is capable of changes or modifications within the scopeof the invention concepts as expressed herein, commensurate with theabove teachings and/or the skill or knowledge of the relevant art. Theembodiments described herein above are further intended to explain bestmodes known by applicant and to enable others skilled in the art toutilize the disclosure in such, or other, embodiments and with thevarious modifications required by the particular applications or usesthereof. Accordingly, the description is not intended to limit theinvention to the form disclosed herein. Also, it is intended to theappended claims be construed to include alternative embodiments.

As used herein, the terms “comprising,” “having,” and “including” (or“comprise,” “have,” and “include”) are used in their open, non-limitingsense.

The terms “a,” “an,” and “the” are understood to encompass the plural aswell as the singular.

Thus, the term “a mixture thereof” also relates to “mixtures thereof.”Throughout the disclosure, the term “a mixture thereof” is used,following a list of elements as shown in the following example whereletters A-F represent the elements: “one or more elements selected fromthe group consisting of A, B, C, D, E, F, and a mixture thereof.” Theterm, “a mixture thereof” does not require that the mixture include allof A, B, C, D, E, and F (although all of A, B, C, D, E, and F may beincluded). Rather, it indicates that a mixture of any two or more of A,B, C, D, E, and F can be included. In other words, it is equivalent tothe phrase “one or more elements selected from the group consisting ofA, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, andF.”

Likewise, the term “a salt thereof” also relates to “salts thereof.”Thus, where the disclosure refers to “an element selected from the groupconsisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof,”it indicates that that one or more of A, B, C, D, and F may be included,one or more of a salt of A, a salt of B, a salt of C, a salt of D, asalt of E, and a salt of F may be include, or a mixture of any two of A,B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, asalt of E, and a salt of F may be included.

The salts, for example, the salts of the non-polymeric mono, di, and/ortricarboxylic acids, which are referred to throughout the disclosure mayinclude salts having a counter-ion such as an alkali metal, alkalineearth metal, or ammonium counterion. This list of counterions, however,is non-limiting.

The expression “one or more” means “at least one” and thus includesindividual components as well as mixtures/combinations.

Other than in the operating examples, or where otherwise indicated, allnumbers expressing quantities of ingredients and/or reaction conditionsare to be understood as being modified in all instances by the term“about,” meaning within +/−5% of the indicated number.

Some of the various categories of components identified for the variouscomposition described herein, including the hair treatment compositions,may overlap. In such cases where overlap may exist between two or morecomponents, a single overlapping compound does not represent more thanone component. For example, a homopolymer of methyl quaternizeddimethylaminoethyl methacrylate may be characterized as both a cationicpolymer component and a thickening agent component. If a particularcomposition is described as including both a cationic polymer and athickening agent, a single homopolymer of methyl quaternizeddimethylaminoethyl methacrylate would serve as only the cationic polymeror only the thickening agent (the compound does not serve as both thecationic polymer and the thickening agent in the same composition).

All percentages, parts and ratios herein are based upon the total weightof the compositions of the present invention, unless otherwiseindicated.

“Keratinous substrates” as used herein, includes, but is not limited tokeratin fibers such as hair and/or scalp on the human head.

“Conditioning” as used herein means imparting to one or more hair fibersat least one property chosen from combability, moisture-retentivity,luster, shine, and softness. The state of conditioning can be evaluatedby any means known in the art, such as, for example, measuring, andcomparing, the ease of combability of the treated hair and of theuntreated hair in terms of combing work (gm-in), and consumerperception.

The term “treat” (and its grammatical variations) as used herein refersto the application of the compositions of the present disclosure ontothe surface of keratinous substrates such as hair. The term “treat,” andits grammatical variations, relates to contacting hair with the hairtreatment compositions of the present disclosure.

The term “stable” as used herein means that the composition does notexhibit phase separation and/or crystallization for a period of time,for example, for at least 1 day (24 hours), one week, one month, or oneyear.

“Volatile”, as used herein, means having a flash point of less thanabout 100° C.

“Non-volatile”, as used herein, means having a flash point of greaterthan about 100° C.

All ranges and values disclosed herein are inclusive and combinable. Forexamples, any value or point described herein that falls within a rangedescribed herein can serve as a minimum or maximum value to derive asub-range, etc. Furthermore, all ranges provided are meant to includeevery specific range within, and combination of sub-ranges between, thegiven ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.

The term “substantially free” or “essentially free” as used herein meansthat there is less than about 5% by weight of a specific material addedto a composition, based on the total weight of the compositions.Nonetheless, the compositions may include less than about 3 wt. %, lessthan about 2 wt. %, less than about 1 wt. %, less than about 0.5 wt. %,less than about 0.1 wt. %, or none of the specified material.
